Firewall Configuration on Systems Running

Supported Red Hat Enterprise Linux Operating

Systems and SUSE Linux Enterprise Server

If you enable firewall security while installing Red Hat Enterprise Linux/SUSE

Linux, the SNMP port on all external network interfaces is closed by default.

To enable SNMP management applications such as IT Assistant to discover and

retrieve information from Server Administrator, the SNMP port on at least one

external network interface must be open. If Server Administrator detects that the

SNMP port is not open in the firewall for any external network interface, Server

Administrator displays a warning message and logs a message to the system log.

You can open the SNMP port by disabling the firewall, opening an entire

external network interface in the firewall, or opening the SNMP port for at

least one external network interface in the firewall. You can perform this

action before or after Server Administrator is started.

To open the SNMP port on Red Hat Enterprise Linux using one of the

previously described methods, perform the following steps:

At the Red Hat Enterprise Linux command prompt, type

setup

and

press <Enter>

to start the Text Mode Setup Utility.

NOTE: This command is available only if you have performed a default

installation of the operating system.

The

Choose a Tool

menu appears.

Select

Firewall Configuration

using the down arrow and press <Enter>.

The

screen appears.
